Abstract: In an embodiment, a forked wearable shim for use in a suspension system, comprising: a shim body including a first planar surface and a second planar surface; a shank portion, the shank portion having an alignment opening extending through the body from the first planar surface through the second planar surface and a fastening opening extending through the body from the first planar surface through the second planar surface located between an end of the shank portion and the alignment opening; a forked-shaped second end having a first prong extending away from the shank portion and a second prong opposite the first prong and extending away from the shank portion; and a first breakaway slot and a second breakaway slot.

Abstract: A front suspension for a front axle of a tractor of an articulated vehicle may include an upper suspension link having an axle center mounting arm pivotally connected proximate a top side of the front axle at the axial center of the front axle, and first and second frame mounting arms extending rearward and pivotally connected to a tractor frame of the tractor. The frame mounting arms may be positioned symmetrically with respect to the axial center of the front axle. The front suspension may further include first and second lower support links pivotally connected proximate a bottom side of the front axle, extending rearward from the front axle, and pivotally connected to the tractor frame. The lower support links may be positioned symmetrically with respect to the axial center of the front axle.

Abstract: A sealing comprises a seal portion and a plate portion fixed to the seal portion. The seal portion can have an undulating configuration of at least one peak and at least one valley, and the plate portion can circumferentially surround the seal portion. The seal portion can be made of a first material and the plate portion can be made of a second material more rigid than the first material. The seal portion can have a radially inward facing contact surface that defines a central opening of the sealing.

Abstract: A rocker support insert for a support rocker comprises a support plate configured to be removably coupled to a top portion of a rocker body; and a support padding fixedly coupled to a top surface of the support plate such that a portion of the top surface of the support plate remains exposed. A top surface of the support padding can define a concave upward-facing contact surface, and the support padding can be thicker than the support plate.

Abstract: A support rocker configured to be pivotally coupled to a rocker attachment interface of a space frame comprises a rocker body having a pivot bore configured to receive therethrough a pivot pin to pivotally couple the rocker body to the rocker attachment interface; and a rocker support insert provided on a top portion of the rocker body. The rocker support insert can be removably coupled to the top portion of the rocker body, and the rocker support insert can define an upward-facing contact surface.
